Diffusion Length of Transition Region Solution

Follow our step by step solution on how to calculate Diffusion Length of Transition Region?

FIRST Step Consider the formula

L dif = \frac{i opt}{q \cdot A pn \cdot g op} - (W + L p)

Next Step Substitute values of Variables

∴

L dif = \frac{0.6mA}{0.3C \cdot 4.8µm² \cdot 2.9E+13} - (6.79μm + 2.1μm)

Next Step Convert Units

∴

L dif = \frac{0.0006A}{0.3C \cdot 4.8E-12m² \cdot 2.9E+13} - (6.8E-6m + 2.1E-6m)

Next Step Prepare to Evaluate

∴

L dif = \frac{0.0006}{0.3 \cdot 4.8E-12 \cdot 2.9E+13} - (6.8E-6 + 2.1E-6)

Next Step Evaluate

∴

L dif = 5.47781609195402E-06m

Next Step Convert to Output's Unit

∴

L dif = 5.47781609195402μm

LAST Step Rounding Answer

∴

L dif = 5.4778μm
